MIFARE DESFire密钥问题
[英]MIFARE DESFire Keys issue
问题描述
I have Mifare DESFire EV1 with 4Kb of memory. 
我有4Kb内存的Mifare DESFire EV1。 I have created an application with AID "000001". 我创建了一个AID为“ 000001”的应用程序。 I want to authenticate with key number 1. However, I get "no such key" error code. 我想用密钥号1进行身份验证。但是，我收到“没有这样的密钥”错误代码。
So probably I don't know the key inside the card, right? 所以可能我不知道卡内的钥匙，对不对？ So how can I find out the keys? 那我怎么找出钥匙呢？ Should I contact the vendor? 我应该联系供应商吗？

"No such key" means that the key number specified is invalid. “没有这样的密钥”表示指定的密钥编号无效。
DESFire keys are numbered from zero. DESFire密钥从零开始编号。 Are you sure you created the application with the correct number of keys (ie at least two)? 您确定使用正确数量的密钥（即至少两个）创建了应用程序吗？
To authenticate with the application master key, use key number 0. 要使用应用程序主密钥进行身份验证，请使用密钥号0。
The initial key value is defined by the card settings. 初始密钥值由卡设置定义。 The default value is written in the manual. 默认值写在手册中。
